Rs. 9800 are invested partly in 9% stock at 75 and 10% stock at 80 to have equal amount of incomes. The investment in 9% stock is:
Answer: Option
Explanation:
Let the investment in 9% stock be Rs. x.
Then, investment in 10% stock = Rs. (9800 - x).
9 | x x = | 10 | x (9800 - x) |
75 | 80 |
3x | = | 9800 - x | |
25 | 8 |
24x = 9800 x 25 - 25x
49x = 9800 x 25
x = 5000.

Let the Face Value of Stock giving dividend 9% be Rs. X, whose Market Value is Rs.75.
Let the Face Value of Stock giving dividend 10% be Rs. Y, whose Market Value is Rs.80.
It is given that,
Total Annual Income = x + y = Rs.9800.
=> y = Rs.9800 - x.
By given formula,
Face Value * Dividend % / Market Value = Annual income.
Annual Income from 1st Stock = 9x/75.
Annual Income from 2nd Stock = 10y/80 = 10 (9800 - x) /80.
Also given that.
Annual Income from 1st Stock = Annual income from 2nd Stock.
=> 9x/75 = 10 (9800 - x) /80.
=> 49x = 9800 x 25.
=> x = 5000.
=> Face Value of Stock giving dividend 9% be Rs.5000.
Let the Face Value of Stock giving dividend 10% be Rs. Y, whose Market Value is Rs.80.
It is given that,
Total Annual Income = x + y = Rs.9800.
=> y = Rs.9800 - x.
By given formula,
Face Value * Dividend % / Market Value = Annual income.
Annual Income from 1st Stock = 9x/75.
Annual Income from 2nd Stock = 10y/80 = 10 (9800 - x) /80.
Also given that.
Annual Income from 1st Stock = Annual income from 2nd Stock.
=> 9x/75 = 10 (9800 - x) /80.
=> 49x = 9800 x 25.
=> x = 5000.
=> Face Value of Stock giving dividend 9% be Rs.5000.

Let 9% in x1 stocks and 10% in X2 stocks and let face value = 100.
Given that equal income from both stocks so, 9x1 (Dividend * no.of stoks 8face value) = 10 x 2.
x1 = (10 * x2)/9 -------> (1)
Total investment = 9800 = 75 * x1 + 80 * x2(i.e. market value * no.of stocks).
Substitute equation 1 in x1 to solve the equation.
x2 = 60.
So investment in X1 is X1 * 75.
INV = 10 * 60 * 75/9,
INV = 5000.

Total income=9800.
Divide income into two parts x,9800-x.
1st part:
income=fnr/100 where n=investment/market value,
income1=(100*x*9)/100.
2nd part:
income2=(100*(9800-x)*10)/100.
We know that, income1=income2.
(100*x*9)/100=(100*(9800-x)*10)/100.
Solve the above equation, the value of x is 5000, which is the investment on 9% shares.
Divide income into two parts x,9800-x.
1st part:
income=fnr/100 where n=investment/market value,
income1=(100*x*9)/100.
2nd part:
income2=(100*(9800-x)*10)/100.
We know that, income1=income2.
(100*x*9)/100=(100*(9800-x)*10)/100.
Solve the above equation, the value of x is 5000, which is the investment on 9% shares.

Hi srikanth
they invest 9800.
this amt is divide into two part (that are x and 9800-x.)
after tat x amt invest for 9% stock and then remain amt is invest into 10% stock.
in problem they also told tat income of both stock are equal so equate both income, now u'll get answer.
I HOPE U UNDERSTAND...

Dear @Souvik,
They are going to invest only 9% and 10% of the stock which is at the rate of 75 and 80 respectively. If they are going to invest the whole amount you can divide it by 100.

Here, They have considered the face value of both to be 100. Right?

Why have we divided the percentage by 75 and 8 receptively?
